There are some numbers with unknown meaning in the original text of the original poster. They may be the numbers used in the illustrations. I wrote them down intact when I translated them.
The lifting platform 3 is an integrated storage platform composed of two upper and lower parking spaces S. A number of grooves 6 are installed on the bottom of the storage table. The chain rolling machine 4 is used to roll up the chain 5 to raise the table, and release the chain to lower the table.
The invention of application 1 (this should be the meaning of the patent application) is to increase the number of layers of the lifting platform to several layers (gt; 2), and use the power of the lifting driving part to raise the table or decline. Use the ground floor as the level used when getting on and off the vehicle, park the vehicle on the platform, and then use the upper floor and the base floor of the ground floor, or at least one of them, as a parking space, that is, use the double-layer lift platform above as a parking space on the upper floor Space usage.
Since the detector is installed on the bearing part of the electric motor of the elevator, it can accurately detect the operation of the lifting process. In addition, since the lift in the entire device is an integrated machine, the installation of the detector is also easy.
The invention of application 4 is based on the potential energy method of maintaining a fixed position of the rotation axis of applications 1 to 3, and adds a detector device capable of detecting peripheral rotation.
